GQ8A033090FAT Description

The GQ8A033090FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 309Ω resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers excellent thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface-mount assembly, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for compact, high-density circuits.

GQ8A033090FAT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in varying environments.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength, ideal for harsh operating conditions.
• Compact QSOP-16 Form Factor: Saves board space with a 4.9mm × 6.02mm footprint and 1.47mm profile, suited for miniaturized designs.
• High Voltage Rating (100V): Supports applications requiring moderate voltage isolation.
• Gull-Wing Termination: Ensures secure soldering and compatibility with automated PCB assembly processes.
